Re: [sumo-user] Opposite direction driving problem

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

For some reason your network was built with option --lefthand even though the area is in a RHT part of the world.

In lefthand networks, the lane numbering is reversed which means that overtaking on the reverse side (towards the right) must be triggered with

                traci.vehicle.changeLaneRelative(vehID, 1, duration)

(The same relative direction index that would be used in RHT networks).

Sumo even provides the warning "Warning: Ignoring indexOffset -1 for vehicle 'v' which is already on laneIndex 0" to indicate that the index you sent is not usable.

regards,

Jakob

Thank you for your reply, 

I still can't implement reverse overtaking

Attach my overtake.py, overtake.route, and use map.xml.

Please help to check my missing

Many Thanks,

Yun

The feature is working in our tests at least. Please provide input files for reproducing your issue.

Hello,

I want the vehicle to overtake on the reverse road for a short time and then return to the forward road

I have read the Opposite-Direction-Driving file and also modified the map to have the <neigh> attribute

But when I use traci.vehicle.changeLaneRelative to test in the simulation, the vehicle still does not switch to the opposite road

Many thanks,

Yun
